摘　　要：通过前期研究,生物柴油混合燃料混合比直接影响到发动机的使用性能,为开发生物柴油发动机控制系统,生物柴油混合燃料混合比车载检测方法成为其重要研究内容。文章依据介电常数测试原理,通过试验分析方法,找出了生物柴油混合燃料混合比与其相对介电常数之间的映射关系,建立了基于介电常数的混合燃料混合比测试模型,并通过试验验证了所建模型的正确性。The performance of biodiesel is researched by our group and other teams before. It shows that biodiesel ratio of biodiesel blend had made a great impact on performance of the engine. Therefore study on the on-line inspection method of biodiesel ratio of biodiesel blend in vehicle is so important. According to experiment processing by permittivity method, we get the linear relationship between the permittivity and biodiesel ratio of biodiesel blend, then establish the test model for biodiesel ratio of biodiesel blend by permittivity method , the model is proved by other experiment.
